Worked on the DaleStudy/daleui repository to deliver unified UI styling and improve interaction consistency across frontend components. Focused on refining focus and hover transitions, consolidating class names and style attributes, and aligning visual elements with design tokens by removing unnecessary focus colors. Utilized CSS-in-JS and TypeScript within a React framework to address visual inconsistencies and enhance accessibility. Added targeted tests to ensure that UI styling changes would not introduce regressions, supporting maintainable and reliable feature development. The work resulted in a smoother, more cohesive user interface and streamlined future enhancements, with an emphasis on consistent theming and maintainable code.
